Cocos Creator教程：加载远程资源的方法与最佳实践

远程 url 带图片后缀名

let remoteUrl = "http://unknown.org/someres.png";
assetManager.loadRemote<ImageAsset>(remoteUrl, function (err, imageAsset) {
    const spriteFrame = new SpriteFrame();
    const texture = new Texture2D();
    texture.image = imageAsset;
    spriteFrame.texture = texture;
    // ...
});

远程 url 不带图片后缀名，此时必须指定远程图片文件的类型

let remoteUrl = "http://unknown.org/emoji?id=124982374";
assetManager.loadRemote<ImageAsset>(remoteUrl, {ext: '.png'}, function (err, imageAsset) {
    const spriteFrame = new SpriteFrame();
    const texture = new Texture2D();
    texture.image = imageAsset;
    spriteFrame.texture = texture;
    // ...
});

用绝对路径加载设备存储内的资源，比如相册

const absolutePath = "/dara/data/some/path/to/image.png";
assetManager.loadRemote<ImageAsset>(absolutePath, function (err, imageAsset) {
    const spriteFrame = new SpriteFrame();
    const texture = new Texture2D();
    texture.image = imageAsset;
    spriteFrame.texture = texture;
    // ...
});

远程音频

remoteUrl = "http://unknown.org/sound.mp3";
assetManager.loadRemote(remoteUrl, function (err, audioClip) {
    // play audio clip
});

远程文本

remoteUrl = "http://unknown.org/skill.txt";
assetManager.loadRemote(remoteUrl, function (err, textAsset) {
    // use string to do something
});
